Because of a different character then the mixture is distilled in a different way too. Therefore include some types of distillation are: Azeotropic distillation, dry distillation, extractive distillation, distillation of frozen (freeze distillation), distillation fractionation, distillation ua (steam distillation) and vacuum distillation.

Based on the process, the distillation can also be divided into batch distillation (Distillation batch) and continuous distillation (continuous distillation). It is called a batch distillation, if done once the process, the materials included in the equipment, processed and then taken the results (distillate and residual). Called continuous distillation if the process is going terusmenerus.Ada flow and the flow of material into the material keluar.Rangkaian distillation equipment widely used in industry is the type of tray and packed-tower tower.

Distillation equipment maintenance.Distillation column must be treated to clean and can optimally use, carried out as follows:

1. The influence of heat on the unit column distillation column condenser and is limited to re pendidih (reboiler), because, in general, the column is isolated, so the loss of heat along the column is relatively small2. For feedback in the form of liquid at bubble point (q = 1) is saturated liquid, heat is given to re pendidih the same as those issued in a condenser. For the tangible feedback in addition to saturated liquid vapor needs, heating is calculated by the balance of heat (enthalpy balance).

Adsorption or separation process penjerapan material is a mixture of gases or liquids, materials that will be separated drawn by a solid surface that absorbs (adsorbent). Usually small particles of absorbent material is placed into a carpet of fixed and fluid then flows through the fixed bed of solid water until it is close to saturation and the desired separation can not last longer. Most substances are pengadsorpsi adsorbent. The materials are porous, and the adsorption took place mainly at the pore walls.

The separation occurs because of differences in seed molecules or due to differences in polarity causes some molecules were attached to the surface more closely than the other molecules. For example, industrial waste washing diadsorpsi batik cloth with color substances using coconut shell charcoal activated. Electroplating wastes containing nickel, nickel diadsorpsi heavy metals with the activated zeolite.Operation of adsorption column

Adsorption column equipped with:

- Bak bait container also functions as a tub overflow reservoir, flow regulator tub, bath effluent reservoir, water pump, flowmeter.- Before the first operated device filled with aquades column to just above the layer of adsorbent. This is intended to avoid air trapped in the column that can interfere with the flow rate.- Equipment operated by passing the raw water sample is gravity (downflow) continuous feedback from the tub using the reservoir to the tub pump speed control runoff. Bak regulator runoff rate is used to obtain pressure and a constant runoff rate.- After the sink rate of runoff flow regulator missed the feedback to get the flowmeter reading secar visual.Flowmeter runoff rate is equipped with 3 pieces regulator tap. In accordance with Figure tap a used to manage the size of the rate of runoff, tap b serves as the entrance to the feed flow adsorption column. B faucets will be closed at the time of the flowmeter calibration condition c faucets open. After the runoff flow rate is stable, closed ddan faucet faucet c b opened. Then the bait will flow into the adsorption column.- Once operational tool with time and a specific runoff rate is the raw water sampling at each outlet, which then conducted an analysis- Repeated for different operating conditions with variations in the rate of runoff, influen concentration variations, and variations in the size of the media.
